Different . . .

Bacalhau is not something I'll ever see in a food store at home.  It's dried salted cod and is a traditional Portuguese food treated this way from before refrigeration became available.  

Already a strongly flavored fish (and strongly smelling I have to say) the preservation process intensifies the flavour while allowing it to be prepared in several different ways.  Although I won't get the chance to cook it myself, I'll be looking out for it on menus over the coming days.  I'm intrigued!
